This article provides a comprehensive profile of individual healthcare expenditure using the 45 and Up Study of over 267,000 NSW residents linked to administrative medical service records. Individuals aged 45 and over consume two-thirds of healthcare expenditure in Australia. We compute annual total healthcare expenditure comprising hospital admissions, emergency presentations, out-of-hospital medical consultations and diagnostic tests and subsidised drugs. The average annual expenditure in the sample is $4334 in 2009 dollars. Less than 3 per cent have zero expenditure. Health service mix varies with age, with the share of hospital expenditure increasing with age. The age trends of total expenditure and its components are then examined by key demographic, socioeconomic and health characteristics, providing important insights into future healthcare demand and a foundation for future research into the drivers of healthcare expenditures and the distribution of health subsidies.
